Why are there two sizes of Sheave Gauges?

The most common question we are asked is when to use a a +5% or a +2.5% Sheave Gauge.
The answer is:+5% Sheave Gauges are designed to determine optimal sheave geometry. They should fit snugly in new or re-machined sheaves. If correctly sized wire rope is run through the sheaves there will be a minimum of friction which should extend the life of the wire rope.+2.5% API Sheave Gauges are used to determine when Maximum and Excessive Wear levels has been reached.

In order to ensure optimal performance of sheaves and wire rope both type of gauges should be utilized.
